摘要
波浪水槽能够模拟波浪的产生、传播以及与结构物的相互作用,提供直观、可靠的数据支持。随着计算机技术和数值方法的快速发展,三维数值波浪水槽逐渐成为港口工程领域的研究热点。利用数值模拟软件FLUENT生成三维数值波浪水槽,并结合ANSYS-FSI模块建立三维有限元与有限体积元耦合模型,可以精确模拟波浪作用于斜坡堤等结构上的整个过程。为验证数值模型的准确性,以在波浪作用下斜坡堤顶胸墙的稳定性为例,比较数值模型与理论公式的计算结果。结果表明,数值模型与理论公式的计算结果基本一致,此三维数值波浪水槽模型可靠。在实际工程应用中,可以利用此数值波浪水槽进行方案比选,提升工作效率,同时与物理模型试验结合,共同为港口工程的设计、施工提供有力支持。
The wave flume can be simulated wave generation,propagation,and interaction with structures,providing intuitive and reliable data support.With the rapid development of computer technology and numerical methods,three-dimensional numerical wave flume gradually becomes a research hotspot in the field of port engineering.In this paper,the three-dimensional numerical wave flume is generated by using the numerical simulation software FLUENT,and the coupling model of three-dimensional finite element and finite volume element is built by combining ANSYS-FSI module,which can accurately simulate the whole process of wave acting on the mounted breakwater and other structures.To verify the accuracy of the numerical model,the stability of the top crown wall of the mounted breakwater under the action of waves is taken as an example,and the results of the numerical model are compared with those of the theoretical formula.The results show that the results of the numerical model and the theoretical formula are basically consistent,which proves that the three-dimensional numerical wave flume model is reliable.In practical engineering application,the numerical wave flume can be used for scheme comparison to improve work efficiency,and combined with physical model test to provide strong support for the design and construction of port engineering.
